The basics of roll form tooling design
The 10-pass example should be fine if you're running non-notched, postcut mild steel. If the section is notched, precut, or high-strength material, you'll need more passes to achieve desired results. Additional passes allow the material to flow through the mill with less strain. Design the Layout and Roll Tooling

After the foil section on the forming table, the moving fabric passes over a series of vacuum boxes and then over a couch roll. Often, a dandy roll is located on top of the forming fabric over the suction boxes. This is a light open structured roll covered with wire cloth, resting lightly upon the surface of the sheet. Its function is to flatten
What Is A Rolling Mill? | Metal Processing Machinery ...
What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.

The basics of roll form tooling design
For each new tooling requirement in a roll form design, take the following five steps: Develop a cross-sectional drawing. Calculate the estimated strip width. Produce a bend progression, or "flower" pattern. Lay out and design the roll tooling around the flower. Incorporate tooling accessories.
Metal Rolling
In shape rolling manufacture, a work piece will often experience different amounts of reduction in different areas of its cross section. One of the goals of roll pass design is to properly design a series of reductions in such a way as to mitigate the relative differences in shape change between areas, in order to avoid material defects.
